EarthCam has been monitoring the construction of One World Trade Center (BKA the Freedom Tower) since day one: October 18th, 2004. (Technically, the cornerstone ceremony took place July 4, 2004, and construction didn't begin in earnest until 2006.)

Yesterday, the skyscraper officially became the tallest building in New York*, and, to celebrate that symbolic milestone, EarthCam released an abbreviated time-lapse video of all the footage it has collected over the past eight years.
